Abstract: In one implementation, a security management system accesses a displacement signature defined in relation to physical contact with a surface and determines that the displacement signature is correlated with a known displacement signature. The security management system then performs an operation in response to determining that the displacement signature is correlated with the known displacement signature.

Abstract: In one implementation, a security management system accesses a trusted location signature and a candidate location signature to determine that the candidate location signature is correlated with the trusted location signature, and establishes a trusted state of an entity in response to determining that the candidate location signature is correlated with the trusted location signature.

Abstract: A reflective display device includes a pixel structure (200) and a liquid crystal (210) containing a dye. The pixel structure (200) provides the liquid crystal (210) with a first tilt state and a second tilt state that are stable absent application of an electric field. In the first tilt state, the liquid crystal (210) is in an untwisted configuration. In the second tilt state, the liquid crystal (210) is in a twisted configuration, and the dye has an effective absorption that is higher than an effective absorption of the dye when the liquid crystal (210) is in the first tilt state.
